1st/Reverse shudder during slow braking.

Trying to get a better idea of whats going on with my FD.

Stock ECU, stock twins.

1st gear (clutch pressed), proceeding to a slow stop (1-5mph), while applying the brakes casually will cause it to shudder. Kind of same feeling as a new standard driver, but a faster shudder.

2nd gear-5th gear (clutch pressed) can't repeat issue.

Reverse (clutch pressed) same issue, once i apply brakes, at a slow speed 1-5mph the car will shudder.

Idle is fine during this, never drops or revs.

What i have checked:

Coilovers, top mounts, bottom mounts.
Visible bushings, etc.
Brake pads have alot of life, and rotors look in good condition.

Any help or suggestions?

Appears to be speed related as it only happens under low speed situations. Have you tried to brake all the way to a stop in second gear? Presumably it will shutter as you get down to the 5 mph range if its related to your brakes. Then the next question is, do you have some special brake kit installed (ceramic brake pads, bigger brakes/rotors, etc.)?

Possibly some runout in the rotors. If the clutch is in, it's not drivetrain related most likely.

Little update, i tested it in an empty lot.

It does it in every gear+reverse. If i put it in neutral it does not repeat the issue.

Sounds like u are not getting total clutch disengagement. You may have a cracked or bent clutch fork.
